Beautify, minify &
validate SQL

No. Formatting only changes whitespace, casing, and line breaks. Query performance depends on logic, indexes, and the database's execution plan, not on how the text is laid out.

Validation here is a heuristic check for unbalanced parentheses, quotes, and BEGIN/END or CASE/END pairs. It flags likely problems but isn't a full parser for every dialect, so it can't guarantee a query is syntactically perfect or repair broken SQL.

Over 20, including Standard SQL, MySQL, MariaDB, PostgreSQL, SQLite, SQL Server (T-SQL), Oracle PL/SQL, BigQuery, Redshift, Snowflake, Spark, Hive, Db2, N1QL, SingleStore, Trino, and DuckDB. A few less common dialects are formatted using their closest compatible syntax, clearly labeled in the dialect list.

No. Formatting, minifying, validation, and image export all run locally in your browser. Fetching a URL you provide is the only network request, made directly from your browser to that URL.

Minify strips extra whitespace and line breaks to shrink the query to as few characters as possible, optionally removing comments too. Format (beautify) does the opposite: it adds consistent indentation and line breaks for readability.

Yes. Turn on "Flatten nested indentation" after beautifying — every clause still starts on its own line, but the leading whitespace that shows nesting depth is stripped.

Yes. The Insights & Warnings panel flags common issues like SELECT *, missing WHERE on UPDATE/DELETE, old-style comma joins, leading-wildcard LIKE patterns, ORDER BY without a row limit, and a few other patterns worth double-checking.

Yes. The Code Screenshot section renders your formatted query like an editor screenshot, with line numbers, the dialect name, a light/dark theme, color scheme presets, and the page URL and tool name in the corners, downloadable as PNG.
